j. The jaws are adapted to receive the typev bearing portion 11 of aVtype slug betweeny their inner or proximate edges by insertion of thetype sluglongitudinally of the jaws,

the inner 'or adj acentedges of the jaws being preferably 'f'bevellediat the entrance or slug receiving end 'as indicated at 12 to Vfacilitatethe insertion of the slug. The sides of the type bearing portion `11 ofthe slug are formed with' grooves 13V intoA Which the sharp edges of thejaws-5 fit, and the bottom of the type' bearing portion 11 of the lslugfits 'against the bottoms 9 of the grooves formed in the jaws, so thatthe'type` bearing portion oftheslug, wheninserted between'the jaws, willbe substantially held against lrocking or tiltingmotion about thelongitudinal 'axis of the slug.'y v i j l, The type slug is .initiallycast in a mold of a kind similar to that used in the casting of ordinarytype high slugs or type bars `used in prlntmg, asfor example, asshown inthe Trun'dle patentv hereinabove referred-to, the

"casting of these slugs inline casting machines v Y of the ordinary orwell known class-.facilitating their production. In casting `the slugsin that manner, theslug is formed initially with a gate 14 which: isjoinedgto the type bearing portion 11 bya relatively thin or constricteneck portion 15, and the: gate portion of the slugy mustbedetachedlioI-removed from the type bearing portion thereof before kthelatter portion of the slug kcanbe used iny avprir'iti'ngl -machine ofthe class having grooves to-receive type barsof short height.

According to the present invention, the slugs are inserted into,the-slug breaking devicez so, that the type'bearingA portion 11thereofis:'receivedlbetween'the jaws in the lmanner hereinbeioredescribedigthe gate por- ,tion 1.4 on thel slug/then projecting freelybeneath the aws, andI bytwisting orswingv i `.ingthe gate `portion ,ofthe slug transverse or intorone' of the, dotted line positions shown inlFig. 2 while the type bearing portionV of the slug is .confined orheldby the jaws, theV Y relatively thin neck'portion ,1510i the slug lprinting lmachine,butf. itis generally pre,

into the printing machinev immediately after the slug gate has beendetached. Figure 3 shows the slug breaking device so mounted on theprinting machine.- In the Yinstance shown, the frameof the slug breakingdevice is ,y formed with an extension 16v which `is adapted to abutvagainst the outer side of one of the end members 17 of the printing maichine, this extension having a lug 18 thereon which is adapted to fitover the adjacent end of the usual tiebar 19 which connects'the endmembers ofl-theprintingmachine, and

a screw 20 maybe passed through the lug 18 and the adj acent end of thetie bar 19 and threaded into the end member of the printing machine andtightened so thatthev lug 18 is drawn down solidly upon the top of theusual tie bar, thus securing the slug breaking device to the end memberoffthe printing machine. A set screw 21 is rpreferably the extension 16Voffthe frameV of the slug breaking device, this set screw being adaptedvto yrest upon the top of the end memberjl? of the printing machine, iadjustment of the threadedthrough another lug 22formed von screw 21serving'to position the jaws 5 of v the slug breaking vdevice verticallywith re 'sp'ect to the printing machinev and *therebyy enabling the slugengaging portions of these jaws tobe alin-ed with 'the type barreceiving 'slot 23 in the adjacentend member of the [printing machine.'A lock nut`2ithreaded' n fthe screw 21 serves to secure the screwinproper adjustment. Y When theslugbreaking deviceV is thuslsej'10o curedto the printing machine it is sup-ported;

firmly in a manner which enables pressureto @be applied convenientlyltothe 'gate of the slug to detach it from the type lb'earingpor- Ytionthereof,v and since thel jaws aline the latter portion of the slug withthe type bar receiving slot in the printing mhne, the type bearingportion of the slug" may beinserted into the printing machine im#mediatelyY after detachment ofthe gate portionof theslug. v

The 'slug breaking device is applicable generally to any printingmachineV of the class .using short height type bars, the printingmachine shownV inthe present'instance being cfa-well kno-wn classemploying a cylinder 25, the periphery ofl which is formedl withr aseries ofcir'c'umferentially spaced grooves 26 toreceive the type barsby a movey n ment longitudinally throughthe slot v23k and intok eachgroove when the latter is in register withthe slot 23, the outerlongitudinal Aedges i of each groovek in vthe printing machine beingformed with in-turned ribs or ledges '27 to engage in the grooves 13' inthe opposite sides of the typebarandthereby retainthelatter IBy holdinglthe slug i its type bearing portion 11 between the grooved edges of thejaws 5 while thegnarrow by the engagementof or thin neck portion 15which joins this portion of the slug with the gate portion thereofbetween the relatively sharp op-posed edges 10 of the jaws, that portionof the slug can be broken and thus detached from the type bearingportion 11 without damaging in any way the type bearing portion of theslug,

this mode of detaching the gateportion from Y the type bearing portionof the. slug being superior tothat heretofore employed whichV consistedin pressing the type bearing portion of the slug against the surface ofa table at an angle and with suicient force to break the gate from thetype bearing portion7 since such a procedure tends to bend or bow therelatively weak type bearing portion so that it does not freely enterthe groove of theY 2.
